Spatial effects and mechanisms of digital economy-enabled food system resilience
Under the new development pattern,the study focuses on the importance of constructing a digital economy to ensure na-tional food security and enhance the resilience of the food system.This paper analyzed panel data of 31 provinces from 2011 to 2020 by using kernel density estimation,standard deviation ellipse,and spatial autocorrelation analysis to explore the spatiotemporal evolution characteristics of the relationship between the digital economy and the food system resilience.This paper also analyzed the impact of dig-ital economy construction on food system resilience based on the Durbin model of dynamic spatial and mediation effect model.The re-sults showed that:①The relation between digital economy and food system resilience showed an overall upward trend with strong spatial heterogeneity.The centre of gravity of the standard deviation ellipse gradually shifted from the northwest to the southeast.②The digital economy had a significant positive impact on food system resilience.This result remained robust even when we try multiple regressions by replacing explanatory variables,excluding municipalities,and changing the weight matrix.The digital information base,digital finan-cial platform,and digital agricultural industrialization all contributed significantly to the resilience of the food system in the region and neighboring regions.③The digital economy contributed to improving food system resilience through advanced technologies.On the a-bove,this paper put forward some suggestions:Optimize resource allocation and promote regional coordinated development.Establish a nationwide agricultural information platform relying on big data and the Internet of Things promote e-commerce and new business such as"Interment+".Keep up with market demand,continuously increase R&D investment,proniote product upgrading,and optimize the grain industry china.Emphasize the cultivation of technical talents and leverage,and play the role of the digital economy in enhancing the capabilities of technical talents.
